I've had this setup in my truck for a while but i never found the time to bring them to their full potential. The sub settings on my head unit (Pioneer DEHP590) are turned wayyy down but it still plays loud. (Is this a good setup?) Also, I'm having a little trouble with the settings on the amp (http://www.mtx.com/caraudio/products...rs/indexTE.cfm). Can anyone give me suggestions on what to set the amp to?
